The Doctor's dreaded adversaries team up with Nazis in this four part audio play to take over the universe. It's a match made in heaven (or is that hell?) since the Daleks, squid like aliens in personal tanks, were always Doctor Who's answer to the Nazis.

Their mission in life is to exterminate non-Dalek life because it is deemed imperfect.

Only the seventh Doctor (Sylvester McCoy) and his companions Dr Elizabeth Klein (Tracey Childs) and Will Arrowsmith (Christian Edwards) stand in their way in the last of the persuasion machine trilogy penned by Alan Barnes and directed by Ken Bentley.

It follows on from Persuasion and Starlight Robbery and will make no sense to anyone who hasn't heard those.

It starts on the planet Azimuth, where the Department of Re-education issues a reminder to all citizens:

"There are no Daleks on Azimuth. There have never been Daleks on Azimuth.

"Twenty years ago, the Daleks did not invade Azimuth. There was no war. There were no death camps. A man named 'the Doctor' did not help liberate Azimuth.

"There are no such things as Daleks. They do not exist. There are no Daleks among us."

Sounds very much like propaganda to me.

"A strange blue box has not appeared in Monument Plaza. Off-worlders named 'the Doctor', 'Elizabeth Klein' and 'Will Arrowsmith' are not at large in the city. For your own safety, should you not see any of the above, report at once to the Department of Re-education, Azimuth Central."

The Dalek's creator Davros, a mainstay of Dalek stories since fourth Doctor Tom Baker's days, makes a welcome re-appearance in the form of Terry Molloy. He was in New Zealand a year ago at the Armageddon Expo in Auckland.

It would be wrong to say I love Davros's appearances, as he's such a twisted individual, but his machinations in this story once again beggar belief.

I don't want to give too much away, but Daleks Among Us is a fantastically fitting conclusion to this interestingly varied trilogy. Each part has its own tone, and this one's nail biting.
